Filtration & Silence Periods Durations

Message Default Minimum Maximum Detail
FP1d 0 0 240 Filtration period 1 duration in minutes
FP2d 0 0 240 Filtration period 2 duration in minutes
FP3d 0 0 240 Filtration period 3 duration in minutes
FP3d 0 0 240 Filtration period 4 duration in minutes
SILd 0 0 12 Silence period duration in hours

The silence period is one during which nothing will run. It overrides all filtrations, the economy cycle, and temperature sampling. Except if temperature drops below 40 degrees. A spa may be installed near a bedroom and need not come on at specific times, for example between midnight and 7 in the morning. Only a user may override the silence timer

Note : Keep the value of any timer to 0 to keep it from running. Filtration timers must be programmed first one first. If the FP1d (first) timer has a duration of 0, Auto Filtration will be in effect and all 4 programmed timers will be disabled.

Code Def Min Max Detail
CLDN 30 60 180 180 Cool Down cycle in seconds. Whenever the heater is turned off the pump keeps running the extra seconds to even the temperature of the heater element and the surrounding water to prevent scale build up and premature heater failure.
ECL 60 180 240 Economy Cycle Length. Time in minutes to specify the intervals between spa temperature sampling when the spa is not in use. During this period the spa is in sleep mode. Temperature is sampled at the end of the period. Press any key to cancel this mode
CHCL 0 60 180 Channel Clear. Time in seconds to clear the air channel and the secondary pump(s) plumbing if the spa has not been used for a period of 24 hours. This prevents water stagnation in the plumbing.
UTO 10 20 60 User Time Out. The time in minutes from starting any device, after which all devices will be turned of, and the spa put in "not in use mode". If you should leave the spa with a pump or light running, it will be turned off after the specified time.
PUF 30 60 180 Post Use Filtration. Time in minutes to perform Post Use Filtration this is the optimal time to filter the spa. When you have finished using the spa, that is when it needs filtration the most. Press the SET key to turn everything off and start this cycle. This cycle is performed only once and after pressing the SET key. It is in addition to the standard filtration cycles. Pressing any other device key will cancel this function.
CALB 194 204 214 This is not a time element. It is one of the distinctive features of the SC1000 and the SC2000 systems. The number is internal and is indicative of what the processor sees as temperature. It is used to calibrate the temperature reading. Increase this value by 1 to decrease the displayed temperature by ½ a degree. Decrease this number by 1 to increase displayed temperature by ½ a degree. For example if the controller is displaying a temperature 2 degrees lower than real temperature, increase the number by 4 to get a correct reading. The total range of this parameter is 10 degrees Fahrenheit. Before doing a calibration Please read warning note at end of this page.
SEND       This menu message has no numerical value. Pressing SET while it is displayed records and saves all changes made to all parameters.
CANC       This menu message also has no value. Pressing SET while it is displayed discards all changes made to all parameters and restores last saved or previous values.


The recommended maximum temperature of a spa is 104°F. The absolute maximum beyond which no person should ever be exposed to is 108°F. When you calibrate the spa temperature you are doing so at your own risk. Obtain an accurate medical thermometer to check against. Please contact ACC for proper procedure or if you do not feel confident.
